Thread: Using a lathe
28/06/2019 20:11:07

In industry, education, or private? The answer will be different for each and will prove irrelevant here :D

Thread: Solid carbide end mills
24/06/2019 18:22:55

Check manufacturer's recommended speeds, if you can't achieve them you will just abrade your endmill.
I've used 0.6mm carbide endmills but at 30000rpm and could probably have used a bit more speed.

Thread: Toyo ML210 Milling Attachment Help Needed
23/06/2019 21:25:28

Another link Here to an old forum archive claims that it uses ER16 collets.

Edited By Bizibilder on 23/06/2019 16:38:32

Yeah, I wish!
I have the milling attachment with 6mm, 8mm and 10mm collets, they don't match my ER collets.

Thread: Mill DRO - How many axis?
23/06/2019 21:23:13

If you go 2 axis leave room to upgrade, you'll probably want to as it's common sense to have three and straightforward penny pinching not to.

Thread: Using a Metal Cutting Disc on the SX2 Mill
23/06/2019 21:18:41

I use 100mm carbide tipped circular saw blades for cutoff in the mill.

Thread: combined BOB with drivers or seperate?
22/06/2019 14:38:38
Posted by fizzy on 14/03/2019 20:01:43:

Im also wondering if the new boards will run with windows 7 64bit.

Mach3 runs fine and only has an issue with the Parallel Port in 64bit

Thread: Chinese tacho - beware
22/06/2019 14:32:15

The stuff you buy from China which is crap is that way for a reason, it's because you're cheap! :D

Thread: Myford Super 7 and ER40 collet chuck
22/06/2019 14:28:25

I went with ER40 because it gives me up to 32mm with extended range collets :D

Thread: Carbide inserts tool holders.
22/06/2019 14:25:12
Posted by Hollowpoint on 16/06/2019 23:43:12:

You could try annealing them. Heat them up and let them cool as slowly as possible.

That's how you harden many of the better Tool Steels :D

Thread: Easy Button Die Storage Solution
20/06/2019 12:09:07

I use 4" x 4" x 1" stackable plastic containers with hinged lids stacked in four 2' tall columns in a cupboard, each box edge is labelled and houses either one size of taps and dies or a range, depending on size and the quantity held.
If you have a job for M6x1 you take the M6 box to the job and you have what you need.

Thread: Mill X axis
19/06/2019 17:30:46

You can buy a variable frequency pulse generator and use it as the input for a stepper driver, Arduino is definitely complicating the job unnecessarily.

Thread: Limitation of a milling machine with low spindle RPM.
18/06/2019 08:58:51
Posted by Ian Thomson 2 on 17/06/2019 13:05:40:

For example the GH18 has a top spindle speed of 1420 rpm. The WM18 has a top speed of 2250 rpm.

That's still a low spindle speed, I have an Emco FB2 head which I run at up to 4000rpm and don't consider that as a particularly high speed.

Thread: Material storage fpr Lathe/other machines
14/06/2019 20:15:01

I have Spur Shelving above head height for long lengths and a 900x600x1800mm 1000kg per shelf rack system with mesh shelves for shorter lengths.

Thread: How to machine Acetal
14/06/2019 20:10:57

I use polished the TC tooling specified for Aluminium when machining plastic, it works very well.

Thread: New vice, good choice?
11/06/2019 16:53:07

A vice of this form was the first which allowed me to machine work square.

I tried many cheaper models first, it would have saved me money to buy a more expensive vice first! :D

Thread: DraftSight no longer free
08/06/2019 17:16:57

Crikey, a disappointment for cheapskates everywhere! :D

Thread: Is CAD for Me?
08/06/2019 17:15:51

I started using CAD/CAM at 50, get stuck in, if you have the drive to do it you will succeed!

Thread: Hexagonal Socket Drive
06/06/2019 21:06:58
Posted by Kenneth Deighton on 06/06/2019 19:36:50:

In my apprenticeship days we still used the hexagon type socket sets , the advantage of them was the sockets being much slimmer than the square drive ones and you could get them into smaller gaps etc.


That will be because a hex is smaller than a square then? :D

Thread: Coolant Flow Rates
06/06/2019 21:03:31
Posted by Nigel Graham 2 on 06/06/2019 20:46:26:

Thank you. Umm, I had specified conventional, not NC, machines.

The provision of cooling and the removal of chips to prevent re-cutting is the same principle on manual or CNC, especially in the absence of a full enclosure.

Thread: mark 1 1/2 student with an inverter
05/06/2019 19:13:12

A friend and I re-wired his Harrison M300 for a VFD, we used all the standard switches re-wired to handle 24V control signals for the VFD so it now works exactly as it did with a 3-phase supply but with the addition of a speed control potentiometer.
